以往的研究表明，幼儿可以区分母语和非母语的语音对比容易。然而，到了10到12个月大的时候，婴儿就像成年人一样，通常很难区分那些在他们的母语中不被用来区分意义的辅音对比。虽然在语音感知的这种变化的时间已被牢固地建立，目前知之甚少的过程或机制，参与这种选择性和适应性重组在非母语语音歧视。本研究的目的是确定是否有一个与年龄相关的变化，在言语感知性能和其他发展中的认知能力之间的关系。共有40个8至10个月大的婴儿进行了测试，在非本地辅音的歧视任务，然后在两个额外的任务（视觉分类任务和对象搜索任务），试图确定是否在非本地辅音感知的变化与这些其他领域的认知/感知功能的变化相一致。结果表明，在任务性能的变化发生在所有三个任务的同步性，这种同步性是不能用简单的年龄效应来解释。这些研究结果表明，域一般认知/知觉能力可能会影响到言语知觉的发展变化的第一年结束的生活。
Previous research has shown that young infants can discriminate both native and nonnative phonetic contrasts with ease. By 10 to 12 months of age, however, infants-like adults-typically have difficulty discriminating consonant contrasts that are not used to distinguish meaning in their native language. Although the timing of this change in speech perception has been firmly established, little is currently known about me processes or mechanisms involved in this selective and adaptive reorganization in nonnative phonetic discrimination. This study was designed to determine if there is a relation between age-related changes in speech perception performance and other developing cognitive abilities. A total of 40 8- to 10-month-old infants were tested on a nonnative consonant discrimination task and then on two additional tasks (a visual categorization task and an object search task) in an attempt to determine whether changes in nonnative consonant perception coincide with changes in these other areas of cognitive/perceptual functioning. The results indicate that changes in task performance occur in synchrony across all three tasks, and that this synchrony is not explained by simple age effects. These findings suggest that domain-general cognitive/perceptual competencies may influence developmental changes in speech perception by the end of the 1st year of life.
